Alex Jbanca c503073f6b perf(LeftJoinModel): Add LRU cache for right model data access 
The right model data access is expensive because we need to search the right model for a matching key on every `data` call. This commit adds a LRU cache to the `data` call, storing by default up to 1000 rows.

The cache mechanism uses a QCache for fast index lookup and a std::list to preserve the access order and to ensure a controlled cache removal.

+ fix compilation errors on ConcatModel and WritableProxyModel
